International Day of Immunology 2026

Every year on 29 April, IUIS and EFIS bring the global immunology community together to celebrate the International Day of Immunology (DoI).  A key highlight of this campaign is the official Day of Immunology webinar, featuring outstanding speakers and timely scientific discussions designed to raise awareness of immunology and explore the annual theme.

We are thrilled to announce this year's theme: “Regulatory T Cells: Guardians of Immune Balance“. 

Like every year, we’ll come together with a live webinar on April 29 at 15:00 CET. Registration is now open for the webinar! You may use this link to sign up for the live webinar and add it to your calendar.  Stay tuned and check back our page for the program. 

Alongside the webinar, we also encourage National Member Societies and yEFIS network to take part by running their own outreach activities—and to compete for the Day of Immunology Awards, which recognize and reward the most impactful and creative campaigns worldwide.

In addition, throughout April, we will feature campaigns, stories, and initiatives led by our community around the world, exploring how immune balance is maintained and why it matters. Join us on social media to spread the word and raise awareness.
